The question asked, verbatim: best payment processing for nonprofits

Brands named, in the order the engine gave

1. Stripe mentioned
   Stripe (with the nonprofit discount) - the default for most orgs
2. EIN mentioned
   Caveats: the discount isn't automatic - you apply with your EIN/IRS determination letter, and you need 80%+ of your Stripe volume to be tax-deductible donations.
3. Zeffy mentioned
   Zeffy - if you're small and fee-sensitive
4. Givebutter mentioned
   Givebutter - best all-in-one that isn't tip-dependent
5. PayPal mentioned
   PayPal - add it as a second option, not your only one
6. Dharma Merchant Services mentioned
   Dharma Merchant Services - if you're processing $10k+/month
7. Square mentioned
   Square - only if in-person giving is central
8. Donorbox mentioned
   Donorbox - capable, but priced poorly

The answer, as recorded

Here's how I'd rank them, depending on where you sit: **1. Stripe (with the nonprofit discount) - the default for most orgs** 2.2% + 30¢ once approved, vs. their standard 2.9% + 30¢. It's the processor nearly every donation platform sits on top of, so you keep flexibility. Caveats: the discount isn't automatic - you apply with your EIN/IRS determination letter, and you need 80%+ of your Stripe volume to be tax-deductible donations. Amex, memberships, ticketing and international cards are excluded or cost more. ([checkoutpage.com](https://checkoutpage.com/blog/stripe-for-nonprofits), [givebutter.com](https://givebutter.com/blog/stripe-for-nonprofits)) **2. Zeffy - if you're small and fee-sensitive** Genuinely $0: no platform fee, no processing fee, no subscription. They survive on optional donor tips at checkout (~80% of donors tip). The tradeoff is real - you're asking your donors to pay Zeffy, and the tip prompt is part of your checkout flow. For a small org where 3% is the difference between a program running or not, it's the obvious pick. ([zeffy.com](https://www.zeffy.com/blog/fundraising-app)) **3. Givebutter - best all-in-one that isn't tip-dependent** Free if donor tips cover it; otherwise 1% on donation forms, 3% on fundraising pages, 5% on events/auctions, plus 2.9% + 30¢ processing. Strong campaign, peer-to-peer and event tooling built in, which saves you buying a second product. ([charitycharge.com](https://charitycharge.com/?p=7834)) **4. PayPal - add it as a second option, not your only one** 1.99% + 49¢ for confirmed 501(c)(3)s. Lower percentage than Stripe but a much higher fixed fee, so it wins on large gifts and loses badly on small ones (on a $25 donation PayPal costs ~99¢ vs Stripe's ~85¢; on $500 PayPal is ~$10.44 vs ~$11.30). Worth offering purely because some donors won't give any other way. ([rallyup.com](https://rallyup.com/learn/paypal-vs-stripe-which-payment-processor-is-best-for-nonprofits/), [societ.com](https://www.societ.com/?p=101868)) **5. Dharma Merchant Services - if you're processing $10k+/month** True interchange-plus: interchange + 0.20% + 11¢ online, + 0.15% + 8¢ in person, $15/month for nonprofits. At volume this beats flat-rate pricing meaningfully, and they have a long-standing reputation for honest, transparent dealing in an industry that doesn't. Not worth the setup below ~$10k/month. ([merchantmaverick.com](https://www.merchantmaverick.com/?p=389), [nerdwallet.com](https://www.nerdwallet.com/article/small-business/dharma-merchant-services-review)) **6. Square - only if in-person giving is central** 2.6% + 10¢, no nonprofit discount. The hardware and point-of-sale experience are the reason to choose it - galas, thrift shops, festival booths. ([bloomerang.com](https://bloomerang.com/blog/nonprofit-credit-card-processing)) **7. Donorbox - capable, but priced poorly** 5.15% + 30¢ all-in standard (2.95% platform + 2.2% Stripe), or $150/month for Pro. Fine product; Givebutter does most of the same work for less. ([zeffy.com](https://www.zeffy.com/compare/zeffy-vs-donorbox)) **One thing worth knowing:** the comparison articles above are mostly published by the platforms themselves - Zeffy's fee comparisons are Zeffy marketing, Givebutter's Stripe guide is Givebutter marketing. The underlying rate numbers check out, but verify current pricing on each provider's own page before committing. **If I had to pick one:** under ~$50k/year raised, Zeffy. Between that and ~$500k, Givebutter or Stripe direct. Above that, get a Dharma quote and compare it against your actual interchange mix.
